两种或两种以上橡胶共混的目的是将单种橡胶的固有性能结合到一起,如提高物理机械性能和加工性能,以及在某些情况下降低生产成本实际应用中,物理共混法简单,成本较低,在橡胶共混技术中应用最广泛。但共混技术仍受限制因为共混困难,尤其是在极性和粘度不匹配的体系中。SBR具有良好的耐磨性和耐裂纹增长性,是最有用的合成橡胶之一,特别是在轮胎工业中,但 The purpose of the two or more rubber blends is to combine the inherent properties of a single rubber, such as improving physical mechanical and processing properties and, in some cases, reducing production costs. Physical blending methods are simple , Low cost, the most widely used in rubber blending technology. However, blending techniques are still limited because of difficulties in blending, especially in systems where the polarity and viscosity do not match. SBR has good wear resistance and crack growth, is one of the most useful synthetic rubbers, especially in the tire industry, but
